GT30R + custom EM

[20Volt]

I found a very good tuner near my place, they're building turbo kits for MR2 and Celica (350+ whp@1.8 vvti).

They're showing some interest about 2.2 20VT and I think I am able to convince them of making some stuff for S2/RS2.

What do you think what is the reasonable price for a GT30R and a custom exhaust manifold?

Almost 1500 $... they can be cheaper than this... and they're in Europe.
What about the EM?

1550$ =1050€ cheap

what would be the spool up and top power for this turbo

1050 € is cheap? I think I can get a better offer from those guys I have spoken before.

You can have some boost at 3500rpm, and this turbo is good for about 500HP.

From the recent RR, i belive the GT30R was really only looked at as a direct replacement for the RS2 turbo giving similar power but better spool up.

Correct me if im wrong tho

I'm revisiting some flow numbers for the GT30R - from memory it's compressor has much more capacity than RS2, but the trick is getting the right hotside for best performance. Nicks car seemed to produce much lower power than I would have expected but I seem to recall there was some sort of problem on the day...

I think a duff knock sensor started playing up so they struggled to get higher boost levels.

Thats right doug. Also i 'think' Nick was using stock bottom end, so low end torque had to be controlled so it didnt end up with banana rods!

I was a bit disappointed as well, but only because I could have prepared the car better before hand.

Mihnea only managed to get it to hold 1.6 bar until around 5500rpm and then dropped it down to 1.5bar. Anything higher and the ECU was retarding the ignition due to detecting knock. I've had a fault code since I bought the car for one of the knock sensors. Really need to change it ASAP.

Turbo dynamics rate the turbo for 32psi - 2.2bar, so there is definately a lot more to come.
Looking at the curves, the spool up looks fast - it starts to really climb around 2750 and has peaked by 3000.

Hopefully, once the sensor is sorted, it'll take a bit more boost....

What happened then?

Just reading throgh this old thread, what happened after you replaced the knock sensor(s)? Did it make a significant and instant improvement etc.? Any info appreciated.

Thanks!
